PHOTOGRAPHIC-FILlvI-PACK ADAPTER.

To all whom "it may concern:

Be it known that l, Josnrrr GODDARD, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Photographic- Film-Pack Adapters, of which the following is a specification.

My present invention relates to improvements in photographic film pack adapters, and it has for its object to provide a simple and improved device of this character whereby a flat package of films may be readily inserted and contained therein for exposure in a camera and in such a manner as to perfectly prevent leakage of light to the interior of the adapter, and the films may be exposed with facility the adapter being co1nposed of relatively detachable sections one of which forms a chamber to receive and hold the film pack and the other section forming a front or closure for such chamber and having the usual exposure opening and opaque slide, novel means being provided for effecting a perfectly light-tight fit between the sections and simple and etlicient devices being provided for detachably connecting the sections, the preferred form of the invention involving a lockable connection whereby the sections are quickly connected and disconnected by a relative sliding movement between them.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing:l igures 1 and 2 are perspective views of the two sections of a film pack adapter constructed in accordance with my present invention, the sections being shown detached; Fig. 3 is a view of the adapter partly in side elevation and partly in section, the two parts of the adapter being shown in unlocked condition; Fig. i is a side elevation of the adapter showing the parts in locked relation and in condition for application to a camera; Fig. 5 represents a transverse section through the adapter as shown in the preceding figures; Fig. 6 is a view similar to Fig. 4: showing the adapter equipped with a slightly different form of catch for retaining the sections Specification of Letters Patent.

of the adapter in operative relation; and

Fig. '7 is a perspective view of the adapter showing the sections in unlocked condition. Similar parts are designated by the same reference characters in the several views.

Film pack adapters constructed in accordance with my present invention are capable of use in connection with the well known film packs wherein the cut films are assembled to form a flat package and the films are provided with tabs which serve to remove the films successively from exposing position.

In the accompanying drawing, I have shown certain embodiments of my invention in which the adapter which receives the film pack and positions it for exposure in the camera is composed of relatively separable sections, one forming a chamber for the pack and the other forming a front or closure, and certain specific devices are provided for locking the sections together and for maintaining a perfectly light-tight fit between them: It will be understood, however, that certain modifications and changes may be made in the detail construction or the relative arrangement of the parts in order that the invention may be applied to the best advantage according to the circumstances of each particular case, and the invention is not limited necessarily to the precise details shown.

In the present instance, the adapter consists of a casing or chamber 1 and a front section or closure 2 which constitute relatively separable sections of the adapter. The casing or chamber 1 may be made conveniently of aluminum or any other suitable material or metal and it is closed at the back and also at its four edges in order to prevent any light from possibly reaching the interior of the film pack and thereby fogging the sensitized films. The longitudinal sides 3 and 4 of the casing or chamher are parallel and the front 5 is provided with a slot or opening 6 which is of a size and shape to receive the usual film-adjusting or manipulating tabs of the pack, these tabs projecting through the slot 6 to the exterior of the adapter in order that they may be conveniently grasped and pulled to remove the films from exposing position.

The front section 2 which detachably receives the casing or chamber 1 may be con veniently formed as a frame of Wood or otherwise, it having an exposure opening 7 and being slotted and grooved to re eive an opaque slide 8, this slide serving to close the exposure opening 7 except at those times when the films are being Xposed in the camera.

According to the present invention, the casing or chamber 1 is loaded by detaching it from the front section, this casing or chamber presenting an unobstructed opening to readily receive the pack, and the chamber or casing 1 containing the pack is then applied to the front section in such a way as to form a. perfectly light-tight fit therewith so as to protect the pack, and de vices are provided for locking and retaining the two sections of the pack in assembled relation. In the arese-nt instance, I prefer to form a pair of longitudinal grooves 9 and 10 in the front section 2 which grooves are of such a width and location as to receive the edges of the longitudinal sides 3 and l of the casing 1, the inter-engaging of the sides of the casing and the grooves of the front section effectually breaking the joint beteen these sections and forming a light-tight connection. Owing to the resulting convenience in manipulation of the parts, I so construct the sections of the adapter as to provide locking devices which are locked and unlocked by a relative sliding movement between the actions, the grooves 9 and 10 serving as guides for the casing or chamber during the locking and unlocking operations. This locking action may be obtained in different ways. In Figs. 1 to f inclusive, 1 provide the front 5 of the casing or chamber with a forwardly directed flange 11 which preferably lies in a plane parallel to the plane of relative movement between the sections or substantially so, and this flange is adapted, when the sections are moved toward locking position, to engage beneath and coiiperate with an overhanging flange or projection 12 which is formed adjacent to the upper or forward end of the front section 2 so that when the flange 11 on the casing passes beneath the flange or shoulder 12 on the front section, the upper or forward ends of the casing and front section are held in close and cooperative relation and with the edges of the sides 3 and 4t engaging in the bottoms of the grooves 9 and 10. The lower or rear ends of the casing and front section are also provided with means for retaining them in close and coiipcrative relation by devices which are connected and disconnected. by the relative sliding movement between the sections. In Figs. 1 to 4 inclusive, the casing is provided with a pair of hooks 13 which may proceed edgcwise from the sides 3 and 4t or the casing and depend below those edges of the sides which engage the grooves, and these hooks are adapted to cooperate with a pair of suitably located pins or project-ions l t which are fixed to the front section 2. The construction is such that when the two sections of the pack are relatively shifted, the flange 11 and the hooks 13 will simultaneously the flange 12 and the projections i l to hold the relatively separable sections of the adapter in cooperative relation. Suitably beveled or wedge surf ces are preferably formed upon the forward ends the hooks 13 as shown to insure drawing of the sections in close relation so as to positively exclude light.

.3. suitable catch is preferably provided to completely lock the sections of the adapter in cooperative relation. in F 1 to linclusive, 1 provide a spring catch 15 waich is capable of operating automatically while the sections are being moved into position, this catch a. shown consisting of a resilient tongue which may be fastened to either of the adapter sections, it being illustrated in the present instance as applied to the front 5 of the casing and it has an aperture 16 adapted to receive a coo erative projection 17 which is fixed to the forward portion of the front section. This projection may be beveled and the forward end of the catch 15 may be beveled or upturned as shown to facilitate engagement of the parts and, moreover, the upturning of the free end of the catch 15 provides a finger portion to facilitate an unfastening of the catch.

.ln that form of the invention shown in F 6 and 7, the casing or pack-receiving hamber l and the front section are formed mbstantially as in the preceding construcion. Somewhat different means, however, is provided for holding the rear portions of the casing and front section in coiiperative relation and a different form of catch is provided for completely locking the adapter sections in co oerative relation. in this instance, the rear wall 18 has its edge bent laterally to form forwardly directed hooks or flanges 19, and the forward face of the front section 2 is PlOVlClB-Cl adjacent to its rear edge with a rabbet 20 to receive the hooks and "langes 19 on the -asing as the la .ter is slid into locking position. The forward portions of the casing and front section of the adaptor may be held in cooperative relation in the manner shown in the preceding figures. in Figs. (3 and 7, l also provide a simple form of catch which may be used in place of the catch 15 in the prcccding instance. This catch 21 is pivotally attached to one of the parts. preferably the rear edge of the front section 2, and ifter the two sections of the adapter have been brought into cooperative relation. this catch 21 may be turned into a position to overlap or cooperate with the rear wall 13 of the casing, thereby completely locking eeaeva the parts in cooperative relation. lhe rear wall of the casing is preferably recessed as at 22 to form a clearance for the catch when the latter has been moved into an inoperative position, thereby permitting the casing to be readily separated from the front section.
